This busty mistress is your new keyholder. She's going to control your dick as well as your dirty mind from now on. You better follow her orders if you don't want to be locked up forever. She'll keep you around her house so you can serve her permanently, clean up and serve her as a butler. And if you behave well she'll let you jerk off from time to time!
Mistress Katja locked your dick up in a chastity belt only a few days ago - and you can't take it anymore just yet? Well, that's bad luck for you! She isn't planning to release your tiny dick any time soon and you'll do whatever your hot mistress commands you to, won't you? You don't want her to lose the key to your CB, do you?
